Why does your Zantedeschia Captain Angelo have yellow leaves? Diagnose the cause and fix it with our step-by-step guide.
Zantedeschia 'Captain Angelo' is highly susceptible to rhizome rot if the growing medium remains saturated. Excess moisture prevents oxygen from reaching the roots, leading to chlorosis (yellowing) of the leaves as the plant loses its ability to transport nutrients.
As a heavy feeder during its growing season, a lack of nitrogen can cause older leaves to turn yellow first. This is common if the plant has been in the same potting soil for several seasons without fertilization.
Calla lilies are sensitive to sudden drops in temperature. If exposed to drafts or temperatures below 55°F (13°C), the metabolic processes slow down, often resulting in yellowing and wilting of the foliage.
While 'Captain Angelo' enjoys bright light, insufficient illumination prevents efficient photosynthesis. This can cause the variegated patterns to fade and the foliage to turn a pale, sickly yellow.
